MOTOR VEHICLE OF ANY KIN-D.

Application filed July 21, 1922. $eria1 No. 576,636.

To all whom it may concern:

Be itknown that I, Fnrnm-uorr Gauss, residing at Oberturkheim, VVurttemherg, Ger many, have invented certain .new and useful Improvements in Motor Vehicles of any Kind, of which the following is a specification;

The present invention relates to improvements in motor vehicles of any description such as automobiles, railroad locomotives, tramway vehicles, traction engines," tractors, trailers, freight cars, and the like, more especially in connection with such motor vehicles of this type which are adapted to run in either direction and are provided with differential gears so that they can'be run at varying speeds.

.lVith vehicles of this kind hand levers are usually arranged at both ends viz, at the front and "rear end of the vehicles so that the control gearing may be operated from both ends of the vehicle.

According to the methods heretofore adopted the gear or hand levers are so connected with each other that any movement imparted to one of the hand levers simultaneously produces the same movementof the hand lever arranged at theopposite end of the same vehicle.

In orderto attain this simultaneously executed movement of both hand levers arranged at the front and rear end of the same vehicle the shafts carrying the hand or gear levers have been heretofore connected with a pair of shafts.

Owing the fact, that with these known constructions,the shafts carrying the hand or gear levers are subjected botl'i to axial displacement and to angular movement when the gears are thrown into engagement the use of a pair of connecting sl'iafts was absolutely necessary. Of these two connecting shafts, one allows the axial displacement of the shaft carrying the gear or handlever,

' whilst the other one allows the angular move ment, or a movement askew, of the shafts carrying the gearing or handlevers.

The improvements according to this in.- vention consists in the application and use of one single connecting shaft instead of a pair of same i used hitherto, and furthermore that through this single connecting shaft both the axial displacement and the angular or skewing motion of the shafts of the two gear or handlevcrs arranged at the two ends of the vehicle are effected. The said shaft that connects the two handlevers arranged at the two opposite ends of the vehicle and may be termed the main-shaft is prevented from axial displacement out of its own plane of movement by mounting the same in. a hearing or in any other suitable supporting element. 7

Owing to the fact that the said connecting shaft is seated'in a bearing the same is not only prevented from moving out of its own plane of axial displacement but moreover to the said shaft is imparted a move- Inentv around its own. axis.

These objects of the present invention are attained by the mechanism illustrated in the accompanying drawing in which: Figure' 1 shows diagrammatically the whole of "the arrangement of the levers in their inoperative position and I Figure 1 is a side view of Figure 1.

In Figure 2 the full lines represent diagramm'aticaly the whole arrangement after the hand or eoi'itrol'levers have been operated and after the shafts of the gear or handlevers have'been subjected coaxial displacement whilst in the dotted lines the levers are shown in their normal or inoperative position.

Figure 3 shows 'in full lines the position of the lovers after the shafts of the gear or handlevers have been given an angular movement, whilst the dotted lines in this Figure 3 indicates the position occupied by the levers after the shafts of the gear or handlevers have been subjectedto axial displacement. I 1

Figure at is a side viewof Figure 3.

a indicates one of the two handlevers arranged at the opposite ends of the vehicle or of the arrangement of levers.

The handl'e'ver a; is firmly attached to one end of the shaftc while at its opposite end the said shaft carries a jointed coupling connecting the shaft 0 with the lever c. This lever c carries at its opposite end a joined coupling f j with jointed coupling Z which connects the shaft (Z with the, lever g; At itsother end the lever y carries a jointed coupling m connected thereby to, and carrying theot-licr end of-the'sliaft f.

in the drawing, which diagraunnatically represents the invention, the said connecting shaft 7'' is carried and supported in a hearing it which permits the movement of this shaft in one plane only.

Figure 1 shows a side view of the lever g. 'llhe connect-ion between the lever and shaft f on the one hand, and between the lever c and s aft f on the other hand is such that the parts connected may be easily moved. I I V The lovers 5/ and ma, also be nade in two parts in order to allow the same to turn with regard to each other. I

The operation of the arrangement described is as follows:' I I I hen the lever Z) after being operated is brought from the inoperative iosition as represented in Figure, 1 into the position shown in full lines in; Figure ,2 owing the axial displacement of this lever Z) the shaft f is caused to rotate. I I I Owing to, thefact that the levers g, and c are arranged in planes situated above and below the shaftf a nd that they. operatein two directionsopposite to each other, the lever a is displaced to thesameextent and in the same direction as the lever b. I The bearing h tn events theshaft f from being axially displaced in a plane different to that ofthe turningmoveinent for its movement being controlledby th'e bearing the said shaft .liHtSt necessarily rotate around its longitudinal axis. I, I

Now if for example lever b is brought from the positionshown in Figure 2 into'the positions represented in Figures 3 and i the shaft is displaced aXiall v, and cohse qnentlv the lever a is displaced in the same direction and to the saine extent as the lever-7).

The technical advantage attained by this invention may l)0 Sl11nli1tll'lZQ(litl lils that with the ,known s vstems one, of the two main shafts serves for the axialwdisplacement and the other, one for the turning the speed changing gear, whilst with the present invention both moveiiientsare effected-as describedby one single main shaft. I v v I The hingedjoints j and 7c connecting the main shaft with the lever c and the joints or and Z connecting the lever g with the shaft f articulate in planes perpendicular to each other. I I

WhatI claim is I 1. In a motor vehicle, the coi bination with change speed gear and a sliaft opera tivelv connected therewith; of devices at each end of said shaft ada 'ited to operate the same in a direction longitudinal of the said shaft and also to.rotatethesaine, said shaft in being submitted to rotation and to longitudinal displacement, being simultaneously exposed to a swinging motion; the above mentioned operating devices at each end of said shaft being so connected to said shaft that when such devices at one end of said shaft are operated, thereby operating said shaft, the devices at the other end of said shaft are also operated in a corresponding manner; means also being provided to enable all movements of said shaft being carried out inthe same plane.

I 2. In a motorvehicle, the combination with change speed gear and ashaft operatively connect'ed therewith; of devices at eachen'd of said shaft adapted to operate the same in a direction longitudinal of the said shaft and alsoto rotate the same, said devices being so arranged that the rotating and longitudinally, displacing movements produced, aretrz'insmitted and imparted in the same sense and in the same direction to the devicesdispo'sed at the opposite end of said shaft; means for taking over said movements, at the opposite end of said shaft; the aforementioned devices for operating said shaft in a direction longitudinally thereof and to rotate the same, comprising a lever extending at right angles to said shaft, and a second lever extending at right angles to said shaft and alsoat right angles to said first-named lever; said first-nan'icd lever being operatively connected at one end to said shaft and at the other end to said second-named lever so as to be adapted to swing freely with relation to said shaft and with relation to said secondaiame'd lever in directions longiti'idinal of same respectively, but to swing with said shaft and said secondnamed lever when said shaft or said second-named lever is rotated.

8. In amotor vehicle, the combination with change speed gear and a shaft operatively connected therewith; of devices at each end of said shaft adapted to operate the same in adirection longitudinal of the saidshaft and also to rotate the same; said devices comprising a lever extending at right angles to saidshaft, a second lever en tending at right angles to said shaft and also at right angles to said first-named lever, a third lever extending at right angles to said shaft but in an opposite direction from said first-named lever, that is to say, at an angleof one ,lihndred and eighty degrees therewith, and a fourth lever extending at riglit angles tosaid shaft and also at right an' es to said third nained leverz said first and third named levers being each operativelvconnected at one end to said shaft and at their other end to said seconi'land fourth-unified levers respectivel as to he adapted to swing freely with relation to said llH shaft and With relation to said secondand fourth-named levers respectively in directions longitudinal of same respectively, but to swing with said shaft and with said sec- 0ndand fourth-named levers when said shaft or said secondor fourth-named levers respectively are rotated.
